Nida is a young woman from the Philippines who travelled to Okinawa to train with Ryu and Ken's master, Sheng Long. When she arrived at the dojo, however, she found it in a poor state and the master sick from poison. Nida tended to Sheng Long as he promised to train her once he regained his health.

She secretly seeks to kill Ryu who she believes was responsible for the death of her father who worked as a police officer. In reality, an evil clone of Ryu, created by M. Bison, was the one responsible. The comic series ended before Nida discovered the truth.
